BEARING;

Specification of Letters Patent.

Patented Dec. 2a, 1913.

To all whom it may concern:

Be it known that I, SYLVESTER H. Jones, a citizen of the United States, residing at Richmond, in the county of Wayne and State 5 of Indiana, have invented certain new and useful Improvements in Bearings, of which the following is a specification.

This invention relates to improvements in & bearings and more particularly to bearings specially adapted for disk furrow-openers disk so constructed that it may be reversed after the wearing side has become worn.

A further object of the invention isto sim plify and make more effective the operation of bearings of this type.

In accompanying drawings Figure 1 1s a side elevation of so much of a furrow-open- A ing device as is necessary to illustrate this invention, looking at the convex side of the.

disk. Fig. 2 is an enlarged vertical sectional View of the same on the line 2-2 of Fig. 1. Fig. 3is a section on the line 3-8 of Fig. 2. Fig. 4 is a detail view of the lower portion ofthe inside of the support.

Like parts are represented by similar characters of reference in the several Views.

In the said drawing, 1 represents a disk of the usual concavo-convex form, provided with an open center, 2 is a support in the nature of a hanger to which the usual dragbar (not shown) may be attached in any suitable manner. Connected to thedisk about the central openin thereof by the bolts 3* is a housing 3 of the usual construction which receives the bearing block 4, which bearing block is of the same'form as those heretofore used in devices of this character, and is connected to the support by a bolt 5; said bearing block being provided with a recess 6' to receive a projection 7 on the boss 2 of the support to hold the same against rotation. The bearing block 4 is provided with a reduced portion 4: which projects through a central opening in the housing 3 and beyond the same for a suitable distance, the outer end of said reduced portion being fitted over the said boss 2 of the support. Located. upon this reduced portion 4 is a circular hardened flat-faced ring or casing 8, disposed against thg1 outside of the housing; this casing being eld against rotation by a projection 9 thereon which extends into a recess 10 in the reduced portion of the hearing block. This casing 8 is formed openon its inner periphery and outer side and located therein is a felt washer 11. Secured to the housing by the same bolts 3 which secure the housing is a pressed steel cap 12, formed with an 0 on center which fits snugly about the re uced portion 4 of the bearing block and which lies closely adjacent to the felt Washer 11.

r In prior devices which employ felt washore for excluding the dirt, the construction has been such that the washer either is rotatedupon or rotates against a more or less v roughened casing which soon wears the felt washer and causes it to roll up in knots and lumps.

In the construction just described it will be seen that the washer is fully protected upon its outer and inner peripheries and inner side by a non-rotating cap 8 and reduced portion 4 of the bearing block and that the closed by the circulanwearing plate 13, alsoattached to the disk by the securing bolts only point where it is exposed to wear is.

3 the wearing plate being designed to take the wear occasioned; by the end thrust of the disk againstthe bearing block so as to save wear upon the disk at this point and obviate the necessity of renewal of the .en tire disk from this cause. 'To this end, it will be seen that the bearin block extends through the central opening in the disk and to a point substantially flush with the convex side of the disk, and in close proximity to the plate. This plate 13 is formed fiat, and the portion-1 of the disk immediately surrounding the opening therein and against which the cover plate lies, is likewise flattoned. The housing 3 is preferably provided with a circular laterally extending flange 3 which is fitted to the circular opening of the disk about the bearing block, and against which the plate 13 is also adapted to lie. Packing in the nature of thin washers 14 and 15 of any suitable material, but preferably asbestos fiber, are interposed respectively between the disk and the plate 13 and housing 3, to exclude dirt at these points. ()wing to the fiat nature of the plate 13 and the central portion of the disk, it will be seen that when the inside of the plate 13 becomes worn to any appreciable extent, it may be readily reversed.

Having thus described my invention, I claim I 1. In a bearing, a fixed bearing block, a rotatable member, a housing carried by said member journaled on said block, a flexible washer fitted to said block, a wearing ring between said flexible washer and the outside of said housing, means for holding said ring and washer against rotation, and a cap carried by said member and in frictional engagement with the exposed side of said flexible washer.

2. In a bearing, a fixed bearing block having a reduced portion, a rotatable member, a housing carried by said member journaled upon said block, a flexible Washer fitted to the reduced portion of said block on the outside of said housing, a wearing ring encircling said reduced portion of the block between said flexible washer and the outside of said housing, means for holding said ring and washer against rotation, and a cap carried by said member and encircling said reduced portion of said block and in frictional engagement with the exposed side of said washer. I

3. In a bearing, a fixed bearing block, a rotatable member, a housing carried by said member journaled on said block, a flexible washer on said block on the outside of saidhousing a wearing ring between said flexible washer and housing and formed to embrace the outer periphery of said washer, means for holding said ring and washer against rotation on said block, and a cap also carried by said member in frictional engagement with the exposed side of said
